BARREL-HOOTP DRIVING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 710,421, dated October 7, 1902.

Application filed April 17, 1899.

To all whom it may concern.-

Be it known that I, WILHELM BURKART, a subject of the King of Prussia, Emperor of Germany, residing at Plauen i. V., Saxony, Germany, have invented a certain new and useful Machine for the Purpose of Driving on Hoops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention has reference to barrel-hooping machines, and provides means whereby the hoops of a cask or barrel may be driven two at a time at one operation of the machine.

The invention is illustrated in the drawings accompanying and forming a part of this specification, wherein Figure 1 shows a side view of a barrelhooping machine constructed in accordance with my invention; Fig. 2, a section on line A B of Fig. 1; and Figs. 3 and 3 illustrate, for convenience in vertical position and on an enlarged scale, parts which are normally horizontal in the machine. Fig. 4 is a partial plan view of Fig. 1.

Similar reference characters refer to like parts throughout the several views.

Reference being had to the drawings, it will be seen that the machine is constructed with the usual standards, which are provided with bearings adapted to receive the screwspindles m, carrying the grooved pulleys 1;. Two cross-bars d d are transversely mounted to slide upon said spindles, one at each end of the machine, and have spring-arms 2, which are provided with rollers 1, adapted to support and automatically adjust the position of the barrel. Said cross-bars d d are caused to move toward each other through the medium of weight Q, connected with the crossbars by chains or ropes passing over the grooved pulleys m. Said spindles are provided with right and left hand screw-threads and carry near their extremities the nuts n, which carry with them the two driver-heads, each provided with six radial plates J. The cross-bars d have fixed to them rods (.8, passing freely through the driver-heads, and are Serial No. 713,390. (No model.)

prevented fronr slipping too far away from the heads by means of stop-nuts on the free ends of said rods. These bars d and the heads move together, except when the bars are clamping and centering a barrel, when they stop and the'driver-heads continue alone.

Each radial plate J has-an arm at extending from it longitudinally of the machine, Figs. 3 3, which arms are bored and threaded to fit the screws g, provided in the plates J, a nut 'i being provided to hold the arms in position. The arms a have inclined inner ends and have pivoted at each side thereof the drivers 70. The three arms a at the bottom of each end of the machine are extended beyond the ends of their drivers, as at a, to receive and support the barrel when it is placed in the machine before the other devices are brought into use. Assuming the machine is ready to receive a barrel, then all the arms are put back, so that the distance between the holders 76 of the arms is a littlein excess of the length of the barrel, while the parts a of the lower arms protrude farther inward. If now the barrel is put in the machine, it will be supported by the wedge-shaped parts at until the arms are moved together and brought into use, and consequently the barrel will be lifted until it is centered in the machine, and the other devices, with the rolls, can be employed to keep the barrel in the right position during the action of the machine.

The drivers is are mounted on pivots O and actuated by springs f to maintain them yieldingly in position A shaft 10 is mounted in hearings in the top of the standards. Said shaft carries a handwheel '1', gear-wheel Z, in mesh with crownwheel Z on screw g at one end of the machine, and at the opposite end gear-wheel Z meshing with crown-wheel Z The drivingshaft w has the drive-wheel o, operated from any prime motor source and the loose pulleys- S S A pulley S has a hollow cone adapted to engage the solid cone 0, a lever it being linked to said solid cone and carrying a weight P, serving to create a certain amount of friction between the cones which determines the limit of pressure transmitted to the hoop-driving arms. The gear-wheel Z on said shaft is in mesh with gear-wheels Z and Z on the screw-spindles m, whereby motion is transmitted to the latter.

After the barrel is placed imposition in the machine, as before described, resting upon the extensions a a ofthe lower arms a. the

hand-wheel r is then turned, whereby through the medium of the shaft to bevel-gears Z Z Z Z screw-spindles g, and nuts 2' the arms a are evenly screwed toward each other in the manner of a support until the drivers 70 are pressed against the hoops. By forcing the wheel S onto the cone 0 through the medium of lever h the spindle w is rotated and also the spindles m, whereby the plates J are caused to move toward each other, thus effecting the driving of two hoops simultaneneously. To drive the next two hoops, the arms a are unscrewed again by turning the wheel 7" until the drivers 7c pass over the driven hoops. The Wheels S S serve to reverse the machine to release the finished barrels.

To center the barrel, the cross-rods d d and the spring-arms 2 are drawn toward each other by the weights Q Q, as described, the return of said cross'rods being effected by means of the plates J and bolts X as soon as the drivers have released the barrels.

Having thus described my invention, I claim' 1. In a barrel-hooping machine, the combination of two heads, plates J, J carried by said heads, the radially-adjustable driverarms 70 operati vely connected with said'plates, cross-rods cl, (1' connected with the plates,

spring-pressed arms pivotally connected with said cross-rods, and means for reciprocating said heads.

2. In a barrel-hoop-driving machine, in combination with the'driving mechanism, the longitudinally-reciprocated heads, the plates J J carried by said heads, the driver-arms operatively connected therewith, manuallyoperated means for radially adjusting said driver-arms, the cross-rods d d connected with said plates, and barrel supports embodyin g spring-arms pivotally connected with said cross-rods and carrying rollers adapted to bear upon the heads of the barrel, substantially as described.

3. In a barrel-hoop-driving machine and in combination with the driving mechanism, the screw-spindles m m, the plates J J having nuts or threaded carriers n mounted upon said spindles, the driver-arms operatively connected with said plates, manually-operated means for radially adjusting said driverarms, the cross-rods (1 cl connected to the plates J J, means for causing said rods to approach each other-, spring-arms pivotally connected with said cross-rods and carrying rollers adapted to bear upon the heads of the barrel, and friction-gear for determining the limit of pressure transmitted to the driverarms, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILHELM BURKART.
